Hi bhartmann,
The missing instruments are part of the Special Edition Volume 2 (formerly known as Extended Library), which you have not licensed. With the Special Edition DVD Boxes that you purchased you received the license for the Standard Libraries (now called: Volume 1), and additionally the samples for Volume 2 in case you want to audition them. It seems that the demo license for Volume 2 has now expired. As you want to continue using the samples of Volume 2, you can purchase the permanent licenses here (bundle price EUR 625 instead of the regular price of EUR 700):
Special Edition Volume 2 Bundle
Since you're obviously using the samples for an album it goes without saying that you'll need to license them. After purchase of the permanent licenses you'll receive an activation code via email which will instantly unlock the additional instruments of Volume 2.
More information about the new naming convention of the Special Editions can be found here.
I hope that helps!
Best,
Stefan
